    • The present invention relates to a digital hearing aid, which models the structures of external ear canals, sizes and shape characteristics of which differ between respective persons, obtains resonance gains generated due to the structural characteristics of the external ear canals, and performs digitization and signal processing to allow the resonance gains to be used as the gain factors of the digital hearing aid, and thus applies the gain factors to digital signal processing units. Further, the present invention proposes a gain obtainment unit capable of taking both resonance gains, generated due to the structural characteristics, and gains, obtained through a hearing test, into account, thus reducing the time required for gain fitting and possible errors, and optimizing the performance of the digital hearing aid for each individual.
    • 本发明涉及一种数字助听器,其对外耳道的结构进行建模,其尺寸和形状特征在各人之间不同,获得由于外耳道的结构特性而产生的共振增益,并且执行数字化和信号 处理以允许谐振增益用作数字助听器的增益因子,并且因此将增益因子应用于数字信号处理单元。 此外,本发明提出一种增益获取单元,其能够考虑由于结构特性而产生的共振增益和通过听力测试获得的增益,从而减少增益拟合所需的时间和可能的误差,以及优化 每个人的数字助听器的性能。
